What's (negative 7) plus (positive 7) plus (negative 17) (adding positive and negative numbers)
Answers
The answer is -17
The negative 7 and positive 7 add up to 0. They are opposites which cancel out. Think of it like being 7 dollars in debt (negative 7) and that debt is fully canceled out by the positive amount of money (positive 7). Put another way, the negative 7 means you go down 7 while the positive 7 means you go up 7.
After the first two terms cancel to 0, the -17 is the only thing left. Adding 0 to any number keeps that number the same.
Final answer:
The sum of (-7) + (+7) + (-17) in mathematics is -17, because a positive and a negative number of the same magnitude cancel each other out.
Explanation:
In the field of mathematics, particularly in arithmetic, a positive number and a negative number can be added together. In this case, you're adding the numbers -7 (negative 7), +7 (positive 7), and -17 (negative 17).
Let's break it down:
- Negative 7 plus positive 7 gives you 0 because a positive and a negative number of the same magnitude cancel each other out.
- Then, add this result (which is 0) to negative 17. The result of this is -17.
So, the sum of (-7) + (+7) + (-17) equals to -17.

17x3 = 51
17x2 = 34
51:34
This is how you work it out: A:B
3:2
3+2=5, 85/5 = 17 (this is what you would have to pay if your part of the ratio was 1)
therefore, to find what A pays, you times the part 1 by 3 (as the ratio is 3:2)
17 x 3 = 51
(likewise, 17x2= 34 which is what B has to pay)

Let x = 3.25 repeating
100x = 325.25 repeating on the 0.25 (you can do this by just moving the decimal place back 2 times, and since repeating decimals go on forever, it's like you just added another "2" and "5" to the front right behind the 3. But it is still mathematically correct. Anyways, we subtract 1x from both sides, but on the right side of the equation, we actually substitute the value of x in, so it would be
100x-x on the left, and
325.25 repeating - 3.25 repeating on the right side.
On the left, 100x becomes
99x
and on the right side, the repeating decimals cancel out to give you
322 (subtracting the 3 still)
so we currently have
99x=322
divide both sides by 99 to get
x = 322/99
which cannot be simplified, so the final fraction is
